If a tenant stops paying rent, the most important thing is to act quickly and keep a proper written record. Confirm the missed payment, document every communication and avoid turning an arrears issue into an informal verbal dispute.
Your lease agreement matters here. It should make the rent due date, payment method, notice process and landlord remedies clear. Strong tenancy paperwork does not remove the problem, but it gives you a much better starting point when payment issues appear.
In practice, the best approach is structured follow-up: written reminders, a clear payment timeline and, where necessary, support from a property manager or legal professional. Delays usually make the position worse. A documented, professional process gives the landlord a better chance of resolving the matter without unnecessary drift.
